I posted in the other thread, but I'll follow this one as well.. I just started taking it this morning, and about 2 hours after the first dose, started feeling kind of cranky and PMS-y... kind of "off" all day. Since I took teh first dose fairly late in the morning, I only got in one more dose, at about 5 pm. I still feel kind of out of sorts, and a slight headache.

I'll give it a few doses, but if the feeling doesn't let up soon, it'll go back to GNC.
